PIPE SLEEVE.

Application led February 13, 1925. Serial N0. 9,1m?.

The present. invention relates to pipe fit-` tings, and more specifically to a two part sleeve coupling adapted for use either upon pipe or hose-lines. l

The primary object of the inventlon 1s to provide an improved pipe sleeve whereby pipe sections may be quickly and eiiiciently connected together without the necessity of requiring the pipe ends to be threaded.

A further object of the invention 1s to provide a device which may be readily clamped about a pipe or hose for the purpose of closing a break or leak in the line.

A still further object of the invention is to provide a two part structure of this character embodying an arrangement whereby the parts .are effectively hingedly connected together, and the retaining means so arranged that the device may be of relatively no greater outer diameter than the screw threaded sleeves now in common use; thus enabling the installation of pipe lines, requiring no more space than the pipe lines connected by the ordinary type of screw threaded sleeve.

Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken, in connection with the accompanying drawing, forming a part of this specification, and in which.drawing:- f

Referring to the drawing 1n detall, and

wherein similar reference characters designate corresponding parts throughout the several views; the letter A may generally designate the improved pipe sleeve embodying separable sections B and C; and D a section of a pipe or hose.

The sleeve A which is formed of two sections preferably of semi-circular shape in cross section may be formed of any desired material such as metal, wood, or any suitablematerial in accordance with which the sleeve is to be used.

Referring first to the section B, which is of uniform thickness -throughout its body, the same has provide'dpn its outer surface, and at the rear edge thereof, a longitudinally extending rabbet 1() extending throughout the entire length of the section. .Formed in this rabbet 10, at the extreme rear' edge-of the section and terminating short of each end of the rabbet, is a longitudinally ex` `tending tongue 11 having its free outer edge f lying i a radial plane with the outer sur` face o the section. Secured to the outer surface vof Vthe section B at the forward edge thereof, as by' rivets or suitable fasten-A ing means 12, are spring clasps 13 which extend beyond the forward edge of the section with a like curvature as that of thesection, and have` provided at their projecting free ends wedge shaped hook portions 14 having rearwardly inclined inner surfaces 15 providing shoulders 1'6 at the inner side of the clasps. These clasps 13'may have their rear end portions bent inwardly and inserted into recesses 17 provided in the sleeve section for aiding in further anchoring the clasps to the section. If desired, the sleeve section B may be recessed on its outer forward surface, so that the clasps may be seated in the recesses with their outer sury faces lying flush with the outersurface of the section. Such construction is not entirely essential however, since the relatively thin fiat spring material from which the clasps may be formed will not materially in*- crease the outer diameter of the-sleeves when being used in places of limited area.

Referring now to thecompanion section C, the same has provided on' its inner surface, and atv the rear edge thereof, a longitudinally extending rabbet 18 extending throughout the entire len h of the section, and which rabbet is prov1ded with an elongated longitudinally extending aperture 19 for receivin the tongue 11 of the section l when assem ling the sleeve sections about a pipe or h ose. Disposed in spaced relation from the Vforward edge of thefsection C, and in alignment with the spring clasps 13, are recesses or depressions 20 conforming tothe general shape of the wedge shaped hook portions 14 of the clasps, and into which the hook por-tions are adapted to `lit when the sleeve sections are in assembled relation. Disposed at the eXtreme forward edge of the section C, and in alignment with each recess 20, are beveled guidewayst 21 which facilitate' the sliding of the s ring clasps 13 into the recesses when assembling the sleeve sections into operative relation about a pipe.

Formed integrally with the section C, and disposed in longitudinal alignment at each side of the recesses 20, are bendable lugs or tabs 22 which are adapted to be bent or clinched over the hooked ends ofthe spring clasps 13, as illustrated in Figure 5, for preventin accidental displacement of the clasps from t el recesses.

A su'table-compressible packing or lining 23 may be provided inwardly of each of the sleeve sections, and .haveits longitudinal edges project slightly beyond the front and rear edges of the sections so thaty when the sections are in assembled relation, atighty joint will be formedl along themeeting edges and by then bringing the forward edges of the sections into confronting relation, the clasps 13 willengage in a holding position in the recesses 20 for rigidly clamping the sections about the member. The lugs 22 may then "be clinched over the ends of the clasps for preventing accidental displacement of the clasps". Should it become desirable t0 remove the sleeve from the pipe, the lugs 22 may first be bent out of holding engagement with the clasps, and then by insertin U a Ascrew driver or the like beneath the wedge shaped hooks 14, the hooks may be sprungout of holding engagement in the recesses 20. While merely two clasps and companion coacting recesses have been shown byWay of example, it is to be understood that any' number of clasps and coactin recesses may be provided should the sleeve e of considerable length.

Various'minor changes may be made to the form of the invention herein shown and described, without departing from the spirit of the invention, or the scope of the following claims.

I claim:

1. A sleeve coupling comprisingr a tubular member divided longitudinally into sepa rable sections, means for hin edly and detachably connecting the sections together along their rear edges, yieldable clasps carried by the forward edge of one of said sections and having projecting portions adapt- 'ed to yieldably seat in recesses provided in the companion section, andbendable lugs formed integral with the companion section and disposed at opposite sides of said recesses adapted to be clinched about the free ends of the clasps for preventing withdrawal of the clasps from the recesses.

2. A sleevev coupling comprising a pair of semicircular shaped sections of uniform thickness throughout their bodies, one of said sections being formed vat its inner surface and at the rear edge thereof with a 1ongitudinally extending rabbet one wall of which is provided with an elongated aperture extending longitudinally of the -rabbet, and said com anion section being formed at its outer sur aceand at the rear edge thereof witha longitudinally extending rabbet providedvat its longitudinal marginal edge with an elongated ton ue having its free outer edge lying inwar y of the circumfer- `ential face of the section, said`tongue when the sections are in-assembled relation fitting into said a erture of the companion section 4 for hinged y and detachably connecting the sections together, and means detachably retaining the sections in tubular formation.

-3.'A sleeve coupling comprising separable semicircular shaped sections having compleinentary rabbets at their rear edges and extending thruout the length of the sections, a radially extending tongue integral with and disposed longitudinally of the pro'ection mation.
